KnocKnown BARREL.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed Ear-ch 19,1914. Serial No. 825,765.

T citizen of the United States, residing in the barrel, of sheet metal or other. suitable ma- 7 city and county of San Francisco" and State of California, have invented new and useful improvements in Knockdown Barrels, of which the following is a specification.

invention relates to knock-down barrels.

The objects of the invention are to provide a simple, substantial, cheaply manufactured terial, which can be quickly assembled or knocked down and reset up; to provide means for holding the sides of such a barrel securely together in the assembled position; and to provide means for securing a practically moisture-proof connection between the bverlappingedges of the barrel. 7 A further important object is to provide a metal barrel with a wooden head, and to so design and arrange the parts that the purtions of the metal barrel expanded to form the crozes for the heads will act as rollers or tires on which thebarrel may be'rolled, the wooden head forming an inward support like the hub and spokes of a wheel against the indentation or collapse of the barrel.

A'further object is to construct the chime sothat it forms a proper seat'and backing for thehead and also to reinforce the chime against collapse or indentation.

Further objects will appear hereinafter. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompany-' ing drawings, in which Figure 1 1s a side elevation, partly broken away, showing'the metal barrel assembled.

Fig. 2 is a cross section of same, showing the joint inthe side of the barrel.

Referring to the drawings, the barrel consists of a sheet A of metal or othersuitable material having such inherent rigidity as to maintain the sheet in the form of a cylin:

der, or allow it to be partially opened when the barrel is knocked down. This sheet is first rolled to form crozes 2 and 3 for the reception of the heads e and 5 respectively;

to form grooves 6 for a plurality andthen w as at -9, to form a. pocket 10 along one lengthwise edge to.

of tip wires l One edge of the sheet is then'folded back upon itself, as at 8, I

receive the opposite edge 11 when bent into cylindrical form. A metalsheet thus rolled and bent is then ready for assembling. This is accomplished as follows: Thefree end- 11 of the rolled sheet is first inserted into the pocket 10, head 4 being inserted at the same time. The tie wires are then applied and fastened, preferably in the manner indicated at 12. The barrel thus assembled is very rigid and substantial in construction and is well adapted as a package for carrying heavy materials, such as nails, cement, and the like. A strip of cloth or other fibrous material 14, saturated with parafiin or other material insoluble in water and running the full length of the barrel, is inserted between the free end l1 of the barrel and the pocket. This makes a positively tight tion is first filled and tamped with the material to be shipped and the head 5 is' then inserted. For the purpose of further reinforcing and strengthening the barrel it may in some instances be desirable to roll a wire or strip of metal 13 in the chime of the barrel. Upon arriving at a destination the top can be easily taken out and the contents removed. Th tie wires fastened in the peculiar manner shown at 12 can be easily removed bya special form of tool, thus per mitting .the sheet to become released and allowing the barrel to fall apart. The sheets of several barrels, together with the heads, can then be nested and shipped back to the factory or packing house, as the nesting of as it were, on which the barrel may "be rolled; the heads 4 and 5 forming inward supports for these rollers.

In order to' form and strengthen the chimes of the barrel, the ends of the sheet constituting the barrel are bent :over to form made of 9 aninwardly and downwardly projecting annular flange '15 which is'bent over so as to approach the surface of the head; this flange 1110 the croze.

The materials and finish of the severalparts of the barrel are such as the experience and judgment of the manufacturer may dictate. I

Having thus described my invention, What I claim and desire to secure by Letters Patent is- A barrel comprising a body of flexible material rolled into cylindrical form and having circumferential convexities adjacent each end thereof forming corresponding concavities within the body constituting crozes, heads engaged in the crozes, there bod being annular grooves immediately below the convexities, the ends of said body having inwardly directed continuous annular flanges, the free edges of which bear against the heads adjacent the crozes, and tie wires engaged in said grooves, said tie wires being under on the inner faces of the heads to positive y hold'the heads in the crozes and in binding engagementwith the free edges-of said flanges.

In testimony whereof I have hereunto set my hand in the witnesses. I

' 'SEWELL A. KNAPP.
